Abstract
The novel fast-drying pressure-sensitive adhesives comprises a polymer of a terminally unsaturated vinyl monomer such as isooctyl acrylate and an emulsifier monomer such as sodium styrene sulfonate plus a phosphate emulsifier, especially certain polyoxyethylene phosphates or salts thereof. Pressure-sensitive adhesive tapes comprise a backing and the novel adhesive. The novel tape is particularly useful as an automotive masking tape, because it both aheres strongly and can be cleanly removed from automotive paints after typical baking cycles. As compared to prior tapes the novel tapes have equal or better adhesive performance, i.e., at least 35 N/dm of peel adhesion, with a faster drying adhesive layer. The tapes can, therefore, be produced more economically. Furthermore, the adhesive bubbling problem formerly seen with paper backings is eliminated.
